4D Printed Self‐Deploying Bio‐Based Scaffolds for the Regeneration of Endoluminal Tissue

open access: yesAdvanced Materials Technologies, EarlyView.
A bilayer self‐deploying tubular C‐shaped scaffold, made of natural polymers and triggerable by humidity, is fabricated via 4D printing for the regeneration of gastro‐intestinal tissue. The choice of the materials and their spatial arrangement is guided by physical and biological evaluation, whereas the geometry of the structure is optimized through ...

A Bistable Assistive Device for Wireless Control of a Dysfunctional Bladder Under Minimal Stress

open access: yesAdvanced Materials Technologies, EarlyView.
This paper presents a wireless system designed to restore bladder function in patients with an underactive bladder (UAB). The system features a multilayered structure, combining a pre‐shaped restoration layer with a spring‐based actuator. The system delivers 95–100% voiding efficiency within a 10‐s activation while ensuring minimal stress on the ...

Adaptive Elastin‐Like Hydrogel with Unidirectional and Controllable Anisotropic Actuation for Soft Robotics and Tissue Engineering

open access: yesAdvanced Materials Technologies, EarlyView.
Fiber‐reinforced elastin‐like tubular scaffolds are engineered to achieve anisotropic and reversible actuation under external stimuli. By adjusting fiber's angle, actuation behavior is finely tuned, enabling distinct actuation responses, even within different regions of the same scaffold.
